1. A radar wave sensing apparatus configured to sense a rotation element, comprising:
- a nanosecond pulse near-field sensor configured to emit an incident radar wave and to receive a reflection radar wave of the incident radar wave hitting on a surface of the rotation element to obtain a repetition frequency variation of the reflection radar wave corresponding to the incident radar wave; and
a control unit configured to calculate a vibration of the rotation element according to the repetition frequency variation.

Abstract
A radar wave sensing apparatus including a rotation element, a nanosecond pulse near-field sensor and a control unit is provided. The nanosecond pulse near-field sensor emits an incident radar wave and receives a reflection radar wave of the incident radar wave hitting on a surface of the rotation element to obtain a repetition frequency variation of the reflection radar wave corresponding to the incident radar wave. The control unit calculates a vibration of the rotation element according to the repetition frequency variation.
